racc fails to install and gives following error on the STDOUT.

D:\Watir>gem install --local racc-1.4.6.gem
Building native extensions. This could take a while…
ERROR: Error installing racc-1.4.6.gem:

I need windows equivalent of the racc-1.4.6.gem by performing following
steps.

  1. Edit the racc-1.4.6.gem for
    “C:\ruby\lib\ruby\gems\1.8\gems\racc-1.4.6\ext\racc\cparse\extconf.rb”
  2. Comment "ENV[“ARCHFLAGS”] = “-arch #{uname -p =~ /powerpc/ ? ‘ppc’
    : ‘i386’}” " line from extconf.rb
  3. Execute following steps and provide the gem.
    % cp -r C:\ruby\lib\ruby\gems\1.8\gems\racc-1.4.6 $HOME
    % cd $HOME/racc-1.4.6
    % rake gem
    % gem install pkg/racc-1.4.6.gem

Note: I don’t have Ruby DevKit.

Thanks in advance.

Ruby DevKit is required to compile extensions that are not provided as
prebuilt-binaries.

Please report to racc bug tracker the issue with Windows:

http://rubyforge.org/projects/racc/

You can suggest the project developers to use rake-compiler to take
advantage of cross-compilation functionality and provide binaries for
Windows.
